AI Technical Summary

Benefits of technology

The patent text describes a new discovery that the daily use of a long-acting β2-adrenoceptor agonist called Olodaterol can help reduce coughing and protect the bronchi. It does not cause addiction or arrhythmias at the low doses used for these effects. Additionally, Olodaterol does not increase heart rate at the doses that reduce coughing and protect the bronchi.

Problems solved by technology

But, these drugs produce side-effects such as drowsiness, nausea, constipation and physical dependence, at their therapeutic doses.

[0030]Other features and advantages of the present invention will become apparent from the following more detailed examples which illustrate, by way of example, the principles of the invention.

Anti-Tussive Activity

[0031]Animals—Male albino Dunkin-Hartley guinea pigs (350-550 g; Charles River WIGA GmbH, Sulzfeld, Germany) were used. The animals were housed in groups of 6 in solid floor cages and allowed free access to water and standard food. The guinea pigs were kept in rooms maintained at a constant temperature (22° C.±2° C.) and humidity (60% ±15%), with a 12 h light cycle. The experiments were approved by the ethical committee Regierungspräsidium Tübingen, Germany.

[0032]OVA asthma model—On days 1 and 2, the guinea pigs were immunised by subcutaneous injection of 0.5 ml per animal of a solution of ovalbumin (OVA) (40 μg / ml) and aluminium hydroxide [Al(OH)3]. On day 14, these sensitised guinea pigs were challenged with OVA by exposure to an OVA aerosol (1.25 mg / ml) for 5 minutes, u...

Abstract

This invention relates to the β2-adrenoceptor agonist Olodaterol or a pharmaceutically acceptable salt thereof,for use in a method of treatment of cough from various origins.

Description

[0001]This invention relates to the β2-adrenoceptor agonist Olodaterol or a pharmaceutically acceptable salt thereof,for use in a method of treatment of cough from various origins.BACKGROUND INFORMATION[0002]Cough is an important defensive reflex of the airway and also a common symptom of respiratory disease. Cough after common respiratory virus infection is transient but is more persistent when associated with conditions such as asthma, chronic obstructive pulmonary disease COPD), idiopathic pulmonary fibrosis (IPF) and cancer.[0003]Although cough is a protective mechanism, chronic and uncontrollable cough belongs to the most debilitating symptoms found in patients with chronic airway diseases (Lee and Undem, 2004). Chronic cough is experienced by more than 16% of the population and represents one of the most complaints that general practitioners or respiratory specialists are confronted with.[0004]The most common anti-tussive treatments are represented by opioids such as codeine, ...
